What nerve Innervates the external oblique muscle?
What nerve Innervates the external oblique muscle?
The external oblique abdominal muscle is innervated by motor branches of the lateral cutaneous branches of the anterior spinal nerves in a segmental pattern. With the exception of the subcostal nerve the motor branches enter the outer surface of the muscle digitation arising from the rib above.
What are the lateral abdominal muscles?
The lateral abdominal muscles comprise the following three muscles:
- Abdominal external oblique muscle.
- Transversus abdominis muscle.
- Rectus sheath.
Is Rectus abdominis deep external oblique?
Muscles of the anterior abdominal wall consists of two vertical muscles located on the midline and bisected by linea alba; Rectus abdominis and pyramidalis and three flat muscles on the anterolateral side arranged from superficial to deep; external abdominal oblique, internal abdominal oblique, transversus abdominis.
What are the 3 oblique muscles?
What movement does the external oblique perform?
The external obliques on either side not only help rotate the trunk, but they perform a few other vital functions. These muscles help pull the chest, as a whole, downwards, which compresses the abdominal cavity. Although relatively minor in scope, the external oblique muscle also supports the rotation of the spine.
What type of muscle is the external oblique?
abdominal muscle
External abdominal oblique (EO) is a flat superficial abdominal muscle located on the lateral side, with anterior abdominal muscle forms anterolateral abdominal wall.
Are the external oblique muscles medial or lateral from the belly button?
External abdominal oblique (EO) is a flat superficial abdominal muscle located on the lateral side, with anterior abdominal muscle forms anterolateral abdominal wall.
What does the external oblique attach to?
| Abdominal external oblique muscle | |
|---|---|
| Insertion | Xiphoid process, outer lip of the iliac crest, pubic crest, pubic tubercle, linea alba, inguinal ligament, anterior superior iliac spine (ASIS) |
| Nerve | Thoracoabdominal nerves (T7-11) and subcostal nerve (T12) |
| Actions | Flexion of the torso and contralateral rotation of torso |
How do you treat an oblique strain?
Apply ice to the affected area for 5-10 minutes at a time three to five times per day. Make sure to wrap the ice in a thin towel to prevent ice burn. The ice will help to minimize swelling and pain in the affected areas. It will also work to limit potential bleeding within the injured tissues.
What do you mean by transverse process fracture?
Transverse Process Fracture. You have fractured a transverse process. There are two transverse processes that extend off each vertebra in the spine, one on each side. This is where some muscles and ligaments of the back attach to the spine.
Can a transverse fracture be maintained with reduction forceps?
A reduced transverse fracture can not be maintained with reduction forceps alone. However, transverse fractures are usually dentate and are intrinsically stable after anatomical reduction. If not, fix the plate to one fragment and then reduce the other fragment onto the plate.
How can I reduce the length of my transverse ulnar fracture?
A small bone lever can be used to reduce transverse, or short oblique, fractures as illustrated. Reduction of overlapping short oblique fractures can sometimes be achieved by twisting a reduction forceps, thereby lengthening the fracture. A reduced transverse fracture can not be maintained with reduction forceps alone.
